Geodetic and Geologic Research on the Geodynamic Network of the City of Zagreb

This paper presents 13 years long interdisciplinary research of geodynamic processes of the area of the City of Zagreb. In 1997, more than 40 specially stabilized stations suitable for high-precise GPS-observation, including two permanent GPS-stations, were measured for the first time. Since then, the campaigns have been regularly performed in the intervals of two to three years. Processing of observation data, always collected using the same equipment and methodology, has been done with scientific software GAMIT, developed by Massachusetts Institute of Technology. Interdisciplinary interpretation of obtained geodetic movements leads to a new scientific insight about geodynamics of the City of Zagreb area. The combined analysis of movements determined by geodetic and geologic methods enabled the determination of structure units movement trends, which mark the areas with lively geodynamic activity causing landslides and earthquakes. The results of this scientific research will be used to delineate zones of potential earthquake hazard or tectonically caused landslides.
